The how of social capital

Flickr/drjausSocial capital is a powerful resource for individuals and communities.  For individuals embedded in dense social networks, these networks and the attendant norms of trust and reciprocity strongly shape individuals’ ability to land jobs, earn higher salaries, and be happier and healthier.  But, even for those not in the networks, having neighbors who know and trust one another affords benefits in some domains:  better performing local government, safer streets, faster economic growth and better performing schools, among other public goods.

For sure social capital can be used toward negative ends: Al Qaeda, the Crips and the Bloods, the Michigan Militia are all examples where group members can accomplish things that they could not accomplish individually (because of  group social capital).  That said, the literature supports that the vast majority of what social capital is used for is to produce positive ends, not negative ones.

But why?  What makes social capital so powerful?

Robert Putnam and I had always focused on information-flows as the key mechanism.  So these social networks:

  • enable individuals to access valuable information: how to get something done, hear of  job leads, learn how better to promote one’s health, find out what is happening in a community, etc.; or
  • help individuals find partners for joint economic transactions (e.g., to know with whom to partner  in business, to close a sale to a friend or a friend of a friend, to locate a neighbor with whom one can exchange tools or expertise); or
  • spread reputations of members (or neighbors or local merchants) which causes all people in these networks to behave in a more trustworthy manner and facilitates altruism.  There is always a short-term gain to be had from cheating someone, but if the social networks quickly spread the information that one cannot be trusted, this short-term gain is swamped by the lost future opportunity to do business with others; thus it becomes more rational to be honest and trustworthy in communities (physical or otherwise) with strong social networks. Individuals are also likely to be kinder and more altruistic toward others because they know that “what goes around comes around” in densely inter-connected networks and communities; and
  • facilitate collective action: it is easier to mobilize others around some shared goal like politics or zoning or improving trash pick-up if others in the  community already know and  trust you, rather than your having to build those social relationships from scratch.

But Connected (by Nick Christakis and James Fowler) raises a different frame for thinking about this issue: network effects or contagion.  Are there properties of the networks themselves that help spread practices, independent of the flow of information?  This is difficult to answer fully since much of their evidence comes from the Framingham Heart Study where  they know who people’s friends are but not what they are doing with each other or what they are saying to each other.

That said, some of their results can be explained by information flows (e.g., political influence, or getting flu shots), but some seem likely to be working through other channels and not through information-flows (e.g., happiness or loneliness cascades).

In these “network effects” or contagion, Fowler & Christakis typically find that the strongest “network” effects are directly with one’s friends (one degree of separation), but these effects also ripple out two more levels to  friends of one’s friends (two degrees) and friends of the friends of one’s friends (three degrees).  As one would expect, much like a stone dropped in a pond, the ripples get smaller as one moves out.  In fact they refer to the “Three Degrees of Influence” Rule that effects are typically only seen up to three degrees out and not further: in the spread of happiness, political views, weight gain, obesity, and smoking.  For example, in happiness, if one is happy, one degree out (controlling for other factors), one’s friends are 15% happier, at 2 degrees of separation they are 10% happier, and they are 6% happier at 3 degrees of separation.  For obesity, the average obese American is more likely to have obese friends, one, two and three degrees of separation out, but not further.  Quitting smoking has diminishing effects out to three degrees.  For political influence, they note a “get-out-the-vote” experiment that shows that knocking on a stranger’s door and urging the resident to support a recycling initiative had a 10% impact on his/her likelihood to vote for the initiative; what was noteworthy to Christakis and Fowler is that the door-knocking made the spouse (who was not at the door) 6% more likely to support the recycling initiative based on communication with his/her spouse.  They conjecture that if this 60% social pass-through rate of political appeals (6% for spouse vs. 10% for person answering door) applied to one’s friends and if everyone had 2 friends, then one person urging friends to vote a certain way would have a 10% impact on one’s friends, a 6% impact on one’s friends’ friends (2 degrees) and a 3.6% impact 3 degrees out.  Multiplying these political effects all the way through, one vote could create a 30x multiplier. [The example is eye-opening and suggests that voting and political persuasion may be less irrational than thought, but also is based on a huge number of assumptions and assumes no cross-competing messages from friends.]

In an experiment on altrusim (explained in this post) Christakis & Fowler found that $1.00 of altruism, ultimately produced $1.05 of multiplier effect ($.20 one ripple out with 3 others and $.05 of altruism two ripples out with 9 others).

Christakis and Fowler, in their book, talk about contagion effects in voting, suicide, loneliness, depression, happiness, violence, STDs, number of sexual partners, binge drinking, back pain, and getting flu shots, among others.  [One summary of many of their findings, which they note, is “You make me sick!”]

Why do these effects only reach out 3 degrees of influence?  Christakis & Fowler suggest 4 potential explanations.

1) intrinsic decay: C&F liken this to a game of telephone where as the information gets repeated, the content gets lost, or the passion and knowledge of the initiator gets dissipated.

2) Instability of ties: because of what is known as “triadic closure“, if A is friends with B and B is friends with C, it is likely that A will become friends with C.  Because of this, closer-in ties between people have more routes connecting them, and further out ties are more dependent on only one pathway connecting them.  For example, assume Abby and Fran were friends 3 degrees removed via Bert and via Charles. If any of these intervening friendships end (say Bert is no longer friends with Charles), Abby loses her tie to Fran.  Thus, these outer ties are much less stable and averaged across all the “3 degrees of influence” friendships, many more may have zero effect because the path of influence dies out as friends change.

3) cross-information:  as one gets further out away from you, say the friends of the friends of your friends, all of these folks are getting lots of cross-stimuli from lots of other sources (many of which may come from different clusters with different habits or values) and these cross-stimuli start to cancel each other out.

4) evolutionary biology: C&F note that humans evolved in small groups that had a maximum of three degrees of separation so it may be that we became more attuned to being influenced by folks who were in a position to alter our gene pool.

So what are the network influences independent of communication.  There seem like 6 possible channels, and often it is hard to separate one from the other, although some may make more sense for the spread of behaviors and others may make more sense for spread of attitudes or emotions:

1) homophily: “Homophily” is the practice of befriending others like you — “birds of a feather flock together.” Being friends with people who are different than you can be stressful.  This is why in mates and in friends we are likely to choose others with whom we have a lot in common — think of arguments you’ve had with friends about where to go for dinner or what is right or wrong with the world when those friends have very different tastes or politics.  For this reason, one reason for increased clustering over time of obese people or smokers or binge drinkers is that it is stressful to be in groups where one is the minority and either constantly noodging others to change their behavior or else your finding yourself frequently doing what your friends want to and what you do not (e.g., eat fast food, smoke, or listen to heavy metal rock music).  As a consequence, people may vote with their feet and form new ties or strengthen ties with others with whom they have more in common.

2) norms/reference groups/culture/peer pressure:   we often measure the reasonableness of our behavior against our friends.  For example, if our teen friends have all had 6 sexual partners in the last year, then repartnering seems far more normal than if one is friends with a group that is heavily monogamous.  Ditto with obesity or smoking or other possible traits or behaviors.

3) subconscious/imitation:  as suggested with “emotion” below, sometimes we mirror others’ behavior or emotions without even thinking about it.  C&F say it makes sense to think of people as subsconsciously reacting to those around them without being aware of any larger pattern.  They talk about processes by which a “wave” at a sporting event takes place, or fish swim in unison, or geese fly in a V-formation, or crickets become synchronized — all of these happen by individuals mirroring those around them.  And in the process, emergent properties of the group arise (much like a cake takes on the taste unlike any of its individual ingredients).

4) emotions: C&F note that emotions actually affect our physical being — our voices, our faces, our posture.  In experiments, people actually “catch emotions”: others become happier by spending time around happy people or sadder by hanging out with depressed individuals.  In experiments, smiling waiters get bigger tips.  It seems quite plausible that cascades like loneliness, happiness, depression, etc. could spread simply from emotional states, independent of any information flowing through these friendships.

5) social invitations for shared action: friends often invite friends to do things — that’s part of friendship. For behaviors, one of the ways they can spread through networks is that, for example, thin friends could invite friends to exercise more, or obese friends could encourage friends to get ice cream together, or smokers could encourage others to leave the dance for a cig.

Connected notes that it is often hard, for example, to tell imitation and norms apart, “When a man gives up his motorcycle after getting hitched, is he copying his wife’s behavior (she doesn’t have a motorcycle) or adopting a new norm (the infernal things are unsafe?)”

Connected also notes how behaviors or attitudes can spread several social links out, even without the intervening link changing.  They suggest that Amy could have a friend Maria who has a friend Heather.  (Amy and Heather don’t know one another.)  Heather gains weight.  Maria, who really likes Heather, becomes less judgmental of her weight and gradually less judgmental of  obesity in general.  Maria doesn’t change her behavior but when Amy stops exercising with Maria, Maria is less likely to pressure her to resume.  Thus Heather’s obesity changes Amy via Maria (by Maria no longer urging her to keep exercising), but Maria doesn’t change her behavior and Amy and Heather don’t know one another.

It’s interesting stuff to ponder and makes one think more expansively about the role and mechanisms of social capital.  It also evokes a conversation with a Saguaro Seminar participant back in 1998 concerning whether black kids and white kids doing sidewalk painting together on the steps of an art museum could promote inter-racial trust, even if the black kids and white kids didn’t know each other, didn’t talk to one another and never met again.  [My hunch is yes, depending on the strength of their pre-existing beliefs about inter-racial trust, but that talking could make the exchange far more powerful.] Another Saguaro participant wondered whether singing together in a chorus helps build social capital, even if one never has a conversation directly with another member of the chorus.  (In the latter example, in addition to being highly unlikely, you are at least getting some non-verbal information over time from the other choral members about their trustworthiness: do they come regularly and on time, do they respectfully listen to and follow the choralmeister?)

I welcome your thoughts.

An ardent plea to our better political angels

Lew Feldstein gave a terrific “Thanksgiving Breakfast” talk touching on themes of the common weal, politics, and the need to find common ground.  This talk was given November 22, 2011 to the New Horizons for New Hampshire (a Manchester non-profit that helps the homeless).  With his permission, I’m posting it.

148 years ago, in 1863, President Abraham Lincoln delivered the Gettysburg Address at the dedication of the Soldiers’ National Cemetery  in Gettysburg, Pennsylvania. It was four and a half months after the devastating battle, and it was a foggy, cold morning. Lincoln arrived about 10 a.m. Around noon, the sun came out as the crowds gathered on a hill overlooking the battlefield. 15,000 people.  A military band played, a local preacher offered a long prayer, and the headlining orator, Edward Everett, spoke for more than two hours. Everett described the Battle of Gettysburg in great detail, and he brought the audience to tears more than once. When Everett finished, Lincoln spoke .

The Gettysburg Address ran for just over two minutes, fewer than 300 words.   Only 10 sentences.

Among the first lines are these, familiar to us all:

‘Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal.

‘Now we are engaged in a great civil war, testing whether that nation, or any nation, so conceived and so dedicated, can long endure. We are met on a great battle-field of that war….’

And so we are, now, in the late Fall of 2011.    Here,  in Manchester, soldiers may not be killing one another, bullets are not flying, but can any of us doubt that, at least metaphorically,  this country is at war, that armies are arrayed against one another,  that…as President Lincoln put it:  ‘we are engaged in a great civil war, testing whether that nation or any nation, so conceived and so dedicated,  can long endure.’

‘We are’, as President Lincoln said, ‘met on a a great battle field of that war.’   As we meet today, a war that tests our county is being fought out across this land in its most disheartening, and discouraging form, by our elected reps in Washington, but also here, in Manchester, right now, and in every town and city, in every state in the nation,  as competing sides gird themselves for the coming elections.

As surely as tanks and cannons can destroy a nation, so can a nation  be destroyed from within, by the unwillingness or inability  to resolve structural problems that, left unresolved, will destroy  the economy and the nation with every bit as much destructive power and finality as bombs and bullets.   Obstinance, adherence to the certitude that I am right and you are wrong, the inability of our leaders to resolve differences, to find common ground, can all be fatal.

We don’t have to look any further than the daily news to see the impact on other nations of their failures to change their ways.

Or, to bring it home, today’s lead story: the failure of “the Super Committee.”

That we reach this point at this season, at Thanksgiving and the Holidays, is especially painful.   That I make this the subject of my Thanksgiving Breakfast talk may feel inappropriate, or uncomfortable, or just plain bad manners.

It is uncomfortable.

But to gather at this time, to mark the eve of  Thanksgiving and  not speak of this, not acknowledge it, would be far worse than uncomfortable.

It would be  criminal.

It is not enough for us, as citizens, to just listen to the news,  curse the enemies, wring our hands,  and then retreat to the cocoons of our daily lives.

We need to be heard.  We need to tell those we elect that they must change how they represent us.

What hubris!  What arrogance!  To believe that your side is so right,  that you have all the wisdom.

We say to them: Will you destroy this nation in the name of saving it?

It is not acceptable to lay all the blame and responsibility on the other side.

We must tell our leaders that they must move.

They must find common ground.

This morning is not the time nor the place to work thorough the competing sides, to assign rights and wrongs.

Thanksgiving starkly juxtaposes the threat that this ugly, unyielding, and unnecessary stalemate  poses to all that we have to be thankful for.

We can do it. We can get through this terrible logjam. We can find our way to a better future.

What could be better evidence of the promise of the American people, the innate goodness and willingness to row together , than this extraordinary institution, New Horizons, which brings 1,000 of us together this morning.

Here we are in the state that:

  • For the past five years has been rated “the most livable state,”
  • For the fourth straight year has been rated the best state in which to raise a child;
  • Has the lowest poverty rate in the country;
  • Has the least amount of income inequality;
  • Has the lowest tax burden; and
  • Has the highest average income.

And yet where one out of four Manchester children are growing up in poverty.

Where scores of families are without shelter every night.

And hundreds of our neighbors cannot feed themselves throughout the year.

As a community we have come together to meet these needs: to house, to  feed , to shelter, to care for our neighbors.

This community takes care of one another.  This is no mean feat in these times.  This is a city infused with high social capital — you know I would work this in — high trust in one another, strong norms of reciprocity,  where helping out is the most natural of things.

And thus it has always been in Manchester going back more than a century.  The city has changed, the business base has changed, the countries of origin of the immigrant and refugee groups that have moved through it have changed, but the strong ties of mutual support, the underlying social capital has remained, strong and enduring.

No small feat.

This trust, this social capital, is the core of why this city is special.  It speaks volumes about the city’s capacity to prosper in good times, and to work through the kinds of big ripping changes in the industrial base, as the very economy of this city has morphed.

I end with thanks, and a prayer.

Thanks  for all who step up to help their neighbors, who put aside differences of  politics and religion and race, even differences between Sox fans and this lonely Yankee fan [Feldstein speaking of himself],  to give of themselves for the common weal, who have built this great agency as testimony to what we can be, what we can do.

And the Prayer that we find common ground.

That our leaders  – on all sides – step away from their certitude, look inward to acknowledge the limits of man, to be far more modest about our individual wisdom, to see for what it is the weakness that compels blind adherence to a single point of view, and look outward to acknowledge that the public that elects them is  far more nuanced  – and far more conciliatory –  then the extremes held up by our elected reps, who through their acts and our own have driven our nation to this terrible impasse.

Please please find common  ground.

Abandon your certitude that only you are right, that only you know the answers.  Don’t destroy our nation.  But take us  together to a better place.

We have done it before.

Get us there again.”

2010 voter turnout up, but not for youth and blacks (UPDATED)

Flickr photo by Dean Terry

Preliminary evidence suggests that voting turnout among all Americans was up in the November 2010 election.  Compared with the last non-presidential election (2006), both voting turnout experts (Curtis Gans and Michael McDonald) agree that turnout among eligible voters rose 1.1-1.2 percentage points (based on preliminary estimates that will obviously change as all ballots are counted and certified). Regardless of whether one likes the outcome in 2010, it is civic good news that more Americans got involved.

Preliminary evidence suggests electoral turnout rose in at least nine states, and significantly in Texas, Florida and Minnesota.  Ohio and Pennsylvania, among other states, seems to have experienced a turnout decline.  [Curtis Gans projects voting turnout at 42 percent of registered voters; Michael McDonald believes that 41.5% of voting-eligible Americans turned out to vote.]  Note: McDonald has now lowered his turnout estimate 1.2 percentage points to 40.3% (VEP Highest Office Turnout, as of 11/8/10).

But the bad news is what voices are being heard or not heard. Voting turnout rates were down among young voters (18-29) and blacks made up a lower percentage of voters in 2010 than in 2008 when Obama’s candidacy excited African-Americans to vote.  For example, blacks made up 12% of voters in 2008 and appeared to make up just 10% of voters in 2010 (based on exit polls).  This drop, if it holds up in more authoritative numbers like the Current Population Survey would  negate this encouraging finding reported in 2008 that the black-white voting gap had disappeared.    [Exit polls suggest that Hispanics maintained their share of the electorate, rising from 7% in 2008 to 8% in 2010, although one would have to compare this rise against their expanding voting-eligible numbers to truly understand whether their political voice was diluted, and if so, how much.]  It wasn’t a simple story of the richest folks’ accounting for more of the votes, since those earning $100,000 or more accounted for 26% of the votes in both 2008 and 2010, but due to the elimination of restrictions on corporate campaign contributions in the wake of the 2010 Citizens United case, the wealthy disproportionately had chances to influence election outcomes even before voters got to their polling places.

Impact of early voting

Early voting turnout as % of votes cast; Source: http://elections.gmu.edu/CPS_2008.html

Citizens voting before Election day continues to increase as the above graph shows from Current Population Survey data.  [The CPS didn’t ask about early voting in the early 1980s.]

Early voting is lower in the off-presidential years, but party experts speculate that a third or more of voters could vote early in the 2010 election, as high or higher than the 2008 presidential election.

“This year, the District and 32 states, including Maryland, allow some form of early voting….Increasingly, states are making it easier for people to vote early, allowing “no excuse” mail-in ballots and automatically sending ballots to voters who voted by mail in the past…. In some states that make early voting especially easy – such as Nevada, where voting booths can be found in health clubs, libraries, supermarkets and shopping malls – it could be much higher. In the last election, 60 percent of Nevadans voted early.” (Washington Post, “Democrats hope early voters will give them an edge“, 10/20/10)  [For a graphic of which states allow voting when, see the Early Voting Center.]

For sure this changes election strategy, pushing candidates not to hold as much of their advertising until the final days of the campaign, to reconsider their approach about last minute negative campaigning, and to invest more resources up front in a GOTEV (get out the early vote) operation.  And in some states, voters may be locking in their votes before they even hear candidates debate, undermining some of the deliberation in our electoral process.

The Post’s headline focuses on the hope for Democrats but signs seem more mixed.  For sure Democrats are trying to rebuild the grassroots machine that helped lift Obama to victory in 2008.  In some states, like Iowa, early voting turnout is up both among Democrats and GOP in 2010.

Democrats hope early voting will change the tide in Senate races in Nevada, Colorado and Washington.   But Politico reports that “In [Nevada’s] Reno’s Washoe County and Las Vegas’ Clark County, Republican turnout was disproportionately high over the first three voting days, according to local election officials. The two counties together make up 86 percent of the state’s voter population.”

Republicans also seem to be early voters in North Carolina. For example, the “largest group of early voters in North Carolina is made up of white Republican men, according to an analysis by the nonpartisan Democracy North Carolina, a campaign watchdog group.” Even though “[d]uring the 2008 Democratic sweep, black Democratic women led all groups during the 17 days of early voting.”

Michael McDonald, voting guru at GMU, summarizes the state of play as “This is the big test election to see if voter mobilization really has an effect on turnout….And at least according to the very earliest early-voting numbers, people who thought the Democrats were going to roll over and play dead, that’s not what’s happening.”

Stay tuned…
